    33[attachment:"UoR24in manual.pdf" Manual from similar University of Rochester telescope.] The original manual furnished with the NMSU telescope has been additionally scanned as a PDF.
    44The telescope is designed to switch between a Cassegrain secondary mirror cell system, offering f/40 and f/75 focal ratios, and a Newtonian secondary mirror cell with a f/5 focal ratio. Ever since the renovation, the Newtonian mirror cell has been installed. Note that although the focal ratio with the Newtonian cell is f/5 we have a coma corrector (2" Astrotech ATCC) mounted in front of the camera, giving an effective overall ratio of f/5.6.
    5 Mounted on the side of the telescope is a 6" two-element refractor guide scope, which is currently unused- note that the instrumentation mounted at the Newtonian focus is directly in front of the guide scope, thus blocking the optical path.

    7 The telescope home position is at declination -40°, and 1 hour east of directly south. Telescope communication and control is via a [http://www.siderealtechnology.com/ Sidereal Technology Servo Controller II].
